LAMP-SHADE .I-IOLDER.

Application filed August 29,1923.- Serial No. 659,911.

To all whom it may concern;

Be it known that I, AUGUST VVILL N- BACHER, a citizen of the United States, and a resident of Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Lamp-Shade Holders, of which. the following is a specification.

This invention relates to a device for use in a shade holder, that is technically known as a harp; whose purpose is to carry an electric lamp at the lower portion and be mounted on a suitable base support, and is adapted to receive a shade or the like at the top or upper portion.

The object of this invention is to provide an improved device of this character that can be very economically and readily constructed by merely casting a wire frame and a threaded stud at two portions, without any machine work being required.

In the accompanying drawing showing one embodiment of my invention, Figure 1 is an elevation, partly in section.

Fig. 2 shows the rod bent to form the frame.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. 4 is a section at the lower end on line H of Fig. 1.

Fig. 5 is an upper end view.

Fig. 6 is a lower end view.

Fig. 7 shows the stud.

As shown the device comprises a frame in the general form of an elongated 100p made bending a single wire rod; a threaded stem secured at one end of the loop, by a cast head; and a yoke having its end portions cast on to the extremities of the loop. The wire rod is formed into a partial circle 2, with the lower portions 3 and 4 extending parallel, and the extremities of these portions are bent inwardly as shown at 5 and 6. The upper part of the loop 2 is-given.

a sharp bend upwardly, as at At the latter portion a threaded stud 8 is secured at this end of the loop, by means of a head 9. The latter is in the form of a casting of suitable metal or alloy of low fusing point,

such as zinc or a suitable composition. This head 9 encloses the bend 7 and also the end portion of the stud 8, as indicated in the sectional view Fig. 3. The end of the stud 8 is preferably flattened, as shown on 10, to prevent its turning when the nut or body screws on this stem, to attach the shade.

At the lower end of the loo'pIthe bent extremities are secured in a yokell having bent ends 12 and :13, that surround the curved ends 5 and Gof the rod. This yoke is also preferably formed of a low fusing composition cast onto the curved ends 5 and 6, as indicated in Figs. 1 and 4E. The middle portion of the yoke is somewhat flattened and extended laterally as shown, and is provided with a screw threaded opening 14 adapted to receive the standard lamp socket.

It is obvious that the head 9, and the yoke 11, can be attached by the same casting operation, by merely placing-the rodand the stud 8 in a suitable mold at one end of the frame, and providing a suitable die to inclose the bent ends 5 and 6, whereby the head 9 and the yoke can be cast on to the frame in the form shown. The rod can be formed of a suitable wire of sufiicient strength for the purpose. The stud 8 is threaded before being cast, so that after the casting operation no finish work is re-.

quired except. to thread the bore 13 which bore can be formed in the die. 'A device of this kind has been found to be very strong and efiicient for the purpose. What I claim is 1 1. A harp comprising a rod into a loop with end portions projecting subthat is formed into a partial circle or loop with end porstantially parallel and the extremities deflected inwardly, a threaded stud adjacent the loop upper end and secured by a head of cast metalthat incloses a loop portion and the end portion of the stud, and a yoke having end portions cast on to the said deflected ends of the rod, with an opening at the middle portion of the yoke in alinement with said threaded stem, said deflected ends preventing accidental disengagement of the rod and yoke.

3. A harp comprising a rod that is formed into a partial circle or loop with end portions projecting substantially parallel, the loop having a sharp short bend at the middle of the rod projecting outwardly, a threaded stud adjacent said bend and secured to the loop by a head of cast metal that incloses the said bend and the end portion of the stud, and a yoke having end portions cast on to the ends of the rod with an opening at the middle portion of the yoke in alinernent with said threaded stem.

4. A harp comprising a rod that is formed into a partial circle or loop with end portions projecting substantially arallel and the extremities deflected inwardly, the loop having a sharp short bend at the middle of 15 and a yoke having curved end portions cast 20 on to the said curved ends of the rod, with a threaded opening at the middle portion of the yoke in alinement with said threaded stem.
